New Yorker article on how people basic decisions about politics

Converse claimed that only around ten per cent of the public has what can be called, even generously, a political belief system. He named these people “ideologues,” by which he meant not that they are fanatics but that they have a reasonable grasp of “what goes with whatâ€?—of how a set of opinions adds up to a coherent political philosophy. Non-ideologues may use terms like “liberal” and “conservative,” but Converse thought that they basically don’t know what they’re talking about, and that their beliefs are characterized by what he termed a lack of “constraint”: they can’t see how one opinion (that taxes should be lower, for example) logically ought to rule out other opinions (such as the belief that there should be more government programs).

Isn’t a person who has an inability to understand basic concepts of cause and effect suffering from a fairly severe mental illness? Terrifying to think that describes 90% of the country

About forty-two per cent of voters, according to Converse’s interpretation of surveys of the 1956 electorate, vote on the basis not of ideology but of perceived self-interest. The rest form political preferences either from their sense of whether times are good or bad (about twenty-five per cent) or from factors that have no discernible “issue content” whatever. Converse put twenty-two per cent of the electorate in this last category. In other words, about twice as many people have no political views as have a coherent political belief system.
